New sunspot 1302 has already produced two X-flares, an X1.4 on Sept. 22nd and X1.9 on Sept. 24th, quickly followed by a strong M7. All three produced CMEs, none of which were Earth directed, but do involved glancing blows, at least. In a few days any CMEs it produces WILL be earth directed.

According to Spaceweather.com:
"The sunspot's magnetic field is crackling with sub-X-class flares that could grow into a larger eruption as the sunspot continues to turn toward Earth."
